5A QUAD POWER HALF BRIDGE s MINIMUM INPUT OUTPUT PULSE WIDTH DISTORTION 200mΩ RdsON COMPLEMENTARY DMOS OUTPUT STAGE CMOS COMPATIBLE LOGIC INPUTS THERMAL PROTECTION THERMAL WARNING OUTPUT UNDER VOLTAGE PROTECTION MULTIPOWER BCD TECHNOLOGY s s s s s PowerSO36 ORDERING NUMBER: STA508 DESCRIPTION STA508 is a monolithic quad half bridge stage in Multipower BCD Technology.
The device can be used as dual bridge or reconfigured, by connecting CONFIG pin to Vdd pin, as single bridge with double current capability, and as half bridge (Binary mode) with half current capability.
The device is particularly designed to make the output stage of a stereo All-Digital High Efficiency AUDIO APPLICATION CIRCUIT (Dual BTL) (DDX™) amplifier capable to deliver 80 + 80W @ THD = 10% at Vcc 35V output power on 8Ω load.
